Vauxhall Astra ecoFLEX

The new Astra range will soon have an ecoFLEX model which emits just 109g/km CO2 and manages 67.3mpg.

The new Astra range already claims a 13.3 per cent average improvement in emissions over the previous model. Now, the ecoFLEX model is 12.1 per cent better than the 1.7 CDTi, which is currently the new range’s most efficient model. This is achieved due to mechanical and aerodynamic improvements.

The Astra ecoFLEX will downsize to a 1.3 CDTi 95PS diesel engine, which will be mated to a five-speed transmission with new ratios to optimise economy. It also comes with a Diesel Particulate Filter (DPF) and re-programmed engine control settings.

To improve aerodynamics, an active aero shutter has been fitted, which opens to allow air past the engine at low vehicle speeds, and then automatically closes at higher speeds to smooth airflow at the front of the car. There’s also improved aerodynamics on the underside of the car, along with a gear change-up light.

This will be the first five-door ecoFLEX-badged Vauxhall to be available in SRi trim, which is designed to give the efficient ecoFLEX a sporty look. S, Exclusiv and SE trims are also available.

The ecoFLEX will have tax benefits, with VED down to £35, and BIK down to 13 per cent, which will take effect from the new tax year in April, when the car will hit UK showrooms with a starting price of £17,920.

There’s also a 100 per cent first year Writing Down Allowance for business fleets.
